3.1 INTRADAY MARKET

Nord Pool offers an intraday market covering the Nordic, Baltic, UK and German markets. The intraday market

supplements the day-ahead market and helps secure the necessary balance between supply and demand in thepower market for Northern Europe.

3.1.1Introduction

The majority of the volume handled by Nord Pool is traded on the day-ahead market. For the most part, thebalance between supply and demand is secured here. However, incidents may take place between the closingof the day-ahead market at noon CET and delivery the next day. A nuclear power plant may stop operating inSweden, or strong winds may cause higher power generation than planned at wind turbine plants in Germany.At the intraday market, buyers and sellers can trade volumes close to real time to bring the market back inbalance.

3.1.2Trading close to real timeAt 14:00 CET, capacities available for Nord Pools intraday trading are published. This is a continuous market,and trading takes place every day around the clock until one hour before delivery. Prices are set based on afirst-come, first-served principle, where best prices come first highest buy price and lowest sell price.

3.1.3Increasingly Importance

The intraday market is becoming increasingly important as more wind power enters the grid. Wind power isunpredictable by nature, and imbalances between day-ahead contracts and produced volume often need to beoffset. The market plays a key role in the development of intraday power trading in Europe. Future prospectsindicate exponential growth, reaching 1.900 GW installed wind Capacity worldwide in 2020 (Source: World WindEnergy Association). This type of market can be a key enabler to increase the share of renewable energy in theenergy mix.

3.2 Day-ahead MARKET

The day-ahead market is the main arena for trading power. Here, contracts are made between seller and buyerfor the delivery of power the following day, the price is set and the trade is agreed.

Today there are around 360 buyers and sellers (called members) on the day-ahead market. Most of them tradeevery day, placing a total of around 2000 orders for power contracts on a daily basis.

3.2.1Driven by PlanningDaily trading is driven by the members planning. A buyer, typically a utility, needs to assess how much energy

(volume) it will need to meet demand the following day, and how much it is willing to pay for this volume,hour by hour. The seller, for example the owner of a hydroelectric power plant, needs to decide how much hecan deliver and at what price, hour by hour. These needs are reflected through orders entered by buyers andsellers into the Nord Pool day-ahead trading system.

3.2.2Setting the Price and closing the deal

12:00 CET is the deadline for submitting bids for power which will be delivered the following day. The tradingsystem feeds the information into a specialist computer system which calculates the price, based on anadvanced algorithm. Put simply, the price is set where the curves for sell price and buy price meet.


7/13


Page 7 of 13

Hourly prices are typically announced to the market at 12:42 CET orlater. Once the market prices have been calculated, trades aresettled. From 00:00 CET the next day, power contracts are physicallydelivered (meaning that the power is provided to the buyer) hour forhour according to the contracts agreed.

3.2.3The cost of transmission constraints

While supply and demand are the key factors determining the hourly market prices, transmission Capacity alsoplays a role. Bottlenecks can occur where power connections are linked to each other, if large volumes need tobe transmitted to meet demand. To relieve this congestion, different area prices are introduced. In otherwords, when Transmission capacity gets constrained, the price is raised to reduce demand in the areasaffected.

3.3 Integrated EuropeThe European Commission has a stated goal of harmonizing the European power markets. The aim is to create apan-European market with closer connecting of power markets to improve the efficient use of energy across

national borders, the European Target Model for electricity market integration.

3.3.1IntroductionAs Europes leading power market, active in nine countries, and, with the Nordics presenting the world withits first deregulated power market, Nord Pool has carved ourselves a position at the very heart of deliveringthe European target model for 2014. We are fully focused on achieving what is best for the future of theEuropean power market and our members.

Under the Target Model, the EU has set up common rules to bring-on efficient use of cross-border Capacityand harmonization of European wholesale power market arrangements. The main features of the model areday-ahead Market coupling and continuous intraday trading to allow cross-border trading of electricity closerto real time; electricity balancing between TSOs; and long-term transmission rights to access capacity oninterconnectors.

That has involved working diligently for the delivery of the Price Coupling of Regions (PCR) and the North-Western European Price Coupling (NWE) launched in February 2014. Since then two extensions of the PCR-coupled area have taken place. Spain and Portugal joined in May 2014, while Italy coupled with France,Austria and Slovenia in February 2015. This full area is called Multi-Regional Coupling and now covers 19countries, standing for about 85% of European power consumption. Nord Pool is as well fully involved in theCross-Border Intraday Market project (XBID).

3.4 Transmission System OperatorsA system operator is responsible for an area to be electrically stable, and for the security of supply in hisarea. A system operator has to be a non-commercial organization, neutral and independent with regard to the

market members.

In the Nordic countries, the system operators have the responsibility for both the security of supply and thehigh-voltage grid (the transmission grid).

The Nordic transmission system operators are Statnett SF(Norway), Svenska Kraftnt(Sweden), Fingrid(Finland) and Energinet.dk(Denmark). The EstonianTSO is Elering and the Lithuanian TSO is Litgrid. InLatvia it is the independent transmission system operator AST. In the UK National Gridis the transmissionsystem operator.

4 Nordpool API

4.1 Authentication

In NordPool authentication is centralized same API credentials can be used to access different APIs. NordPool

4.1.1Basic Analysis

4.1.1.1Three Steps are required for get API Working

1. Request for access Token2. Get Token from API3. Request for required resources along with API.

4.1.1.2Access Token Characteristics

1. ClientEach API exposed by Nord Pool can be only consumed by well-defined API clients. API clients are

defined by Nord Pool Spot. API client definition is publicly distributed.2. API UserIn order to access API, each API consumer is given from Nord Pool API username and password.

Password is a secret, thus should be kept in well protected safe place. API consumers are fullyresponsible for protecting the password.

3. ScopeScope of the token determines with which APIs in NordPool it can be used.

4. ExpirationExpiration indicates how long token is valid. Once token expires API user need to request for a new

token from Nord Pool authentication service.

4.1.2Technical Details

4.1.2.1Token Request

Token can be requested from publicly exposed Nord Pool authentication service. HTTPS protocol isused for requesting and receiving the token.

4.2 Request Signature

4.2.1Basic Analysis

In order to strengthen security for placing/updating/removing fragile resources (e.g. orders), request

signature of the requesting party is required.

Signature is a Hash-based Message Authentication Code (HMAC) constructed from the request andcomputed by using the SHA256 algorithm, and then encoded by using Base64 encoding.

More details regarding implementation to be provided later.

NOTE: For the testing period signing has been turned off.
